如何僅在我的應用程序中獲取運行線程

Question

我正在嘗試獲取應用程序中的所有活動/正在運行的線程。 我寫了下面發布的代碼，並且得到了下面發布的結果。 實際上，發布的輸出中沒有任何線程屬於我的應用程序，除了

07-10 15:36:48.621 19333-19624/eu.men.m2sapp D/GcmIntentService: thread.toString():Thread[IntentService[GcmIntentService],5,main]

1）5號代表什么？

2）似乎“ getAllStackTraces”會檢索系統范圍內的所有活動線程，但是如何獲得僅在我的應用程序中運行的線程？

代碼 ：

Set<Thread> threadSet = Thread.getAllStackTraces().keySet();
Thread[] threadArray = threadSet.toArray(new Thread[threadSet.size()]);
Thread thread = null;
for (int i = 0; i < threadArray.length; i++) {
    thread = threadArray[i];
    Log.d(TAG, "thread.toString():" + thread.toString());
}

輸出 ：

07-10 15:36:48.621 19333-19624/eu.men.m2sapp D/GcmIntentService: thread.toString():Thread[IntentService[GcmIntentService],5,main]

Answer 1

實際上，發布的輸出中沒有任何線程屬於我的應用

所有這些線程都屬於您的應用程序進程。 大多數都來自框架，而不是您的代碼。

似乎“ getAllStackTraces”會檢索系統范圍內的所有活動線程

不，它將在您的進程中檢索線程。

如何獲得僅在我的應用程序中運行的線程？

你已經是

5代表什么？

我認為這是線程優先級。
